A double blind study with Solcoseryl compounds in ophthalmic gel and with 2.4% cystein in ophthalmic gel was performed in the period 1985-1988; it was used in 18 cases: with chronic recurrent keratitis (11 patients) and sicca keratitis (7 patients). Observed was the influence of these compounds on the epithelialization of the cornea, on the improvement of corneal transparency, the diminutation of the troubles connected with dessication of the eye in sicca keratitis. In spite of the small number of cases the observations were interesting. In patients with a chronic recurrent keratitis the influence of both compounds showed to be beneficial for the condition of the cornea. In patients with keratitis sicca one could observe a better tolerance of the Solcoseryl ophthalmic gel which could be applied for a longer period in comparison with cystein in gel.

The rapid, simple, and sensitive detection of nucleic acid biomarkers plays a significant role in clinical diagnosis. Herein, we develop a label-free and point-of-care approach for isothermal DNA detection through the trans-cleavage activity of CRISPR-Cas12 and the growth of gold nanomaterials in agarose gel. The presence of the target can activate CRISPR-Cas12a to cleave single-stranded DNA, thus modulating the length and number of DNA sequences that mediate the growth of gold nanoparticles (AuNPs) or gold nanorods (AuNRs).

Fungal keratitis is a severe ocular infection caused by pathogenic fungi, leading to potential vision loss if untreated. Current antifungal treatments face limitations such as low solubility, poor corneal penetration, and limited therapeutic options. This study aimed to develop a thermosensitive in situ gel incorporating ketoconazole nanoparticles (NPs) to enhance drug solubility, stability, and antifungal activity.

The eyes are easily stimulated by external factors, which can cause inflammation. Anti-inflammatory drugs are usually used to inhibit the production of inflammatory factors. Many nonsteroidal anti-inflammatory drugs have been used for the eye, but due to the poor solubility of meloxicam, there are currently no marketed meloxicam preparations for the treatment of eye diseases.

Posterior segment ocular diseases, such as diabetic retinopathy, age-related macular degeneration, and retinal vein occlusion, are leading causes of vision impairment and blindness worldwide. Effective management of these conditions remains a formidable challenge due to the unique anatomical and physiological barriers of the eye, including the blood-retinal barrier and rapid drug clearance mechanisms. To address these hurdles, nanostructured drug delivery systems are proposed to overcome ocular barriers, target the retina, and enhance permeation while ensuring controlled release.
